【摘要】 提出一种新的最小条件法。用坐标轮换法将最小条件法的目标函数多维无约束优化转化为一维优化,然后用进退法确定搜索区间,最后以黄金分割法进行一维寻优。辅以MATLAB软件完成了无基准任意位置平面曲线轮廓度误差的快速精确评定,并设计人机交互界面实现评定结果可视化。最后通过算例证明算法的可靠性。更多还原

【Abstract】 A novel minimum condition method was proposed. Multi dimensional unconstrained optimization of objective function was transformed into one-dimensional optimization using method of coordinate rotation.Advance and retreat method was used to determine the search interval and then it was optimized by golden section method.The evaluation of profile error was completed by MATLAB.It could be operated easily and the error was shown with diagrammatic view.The testing results show that the algorithm is correct.更多还原
